A Simple Economic Train Shuttle Circuit Part two

I had a need for a ‘one hit’ shuttle service, or limited runs, so when switching on, the train ran once (or a set number of times) up and down the track between stations and then stopped at its original departure point.

This was achieved by adding an extra timer board (also available on Ebay for about $5) that was somewhat different to the continuous timer cycling board. This is a ‘Signal Activated Timer’].
